Summary

This trial will compare a new drug (SG) to current treatments for metastatic breast cancer to see if it can improve life spans. Primary objective is to compare its effect on progression-free survival (PFS).

Who is the study for?
This trial is for adults with HR+/HER2- metastatic breast cancer who've had disease progression despite endocrine therapy. They must have a sample of tumor tissue available, not be candidates for further endocrine treatment, and have adequate organ function. HIV-positive participants need controlled infection on ART. Participants must agree to use contraception and should not be eligible for curative intent therapy or have received certain prior treatments.
What is being tested?
The study tests if Sacituzumab Govitecan (SG) extends the time without cancer growth in patients with HR+/HER2- metastatic breast cancer compared to standard treatments like Paclitaxel, Nab-paclitaxel, or Capecitabine. It measures how long patients live without their disease getting worse.
What are the potential side effects?
Sacituzumab Govitecan can cause side effects such as nausea, diarrhea, hair loss, fatigue, low blood cell counts leading to increased infection risk or bleeding problems. Standard chemotherapy drugs may also cause similar side effects including allergic reactions.
